Very interesting, I certainly agree that simply embodying this higher energy will aid in uplifting the whole. As for visions, I have had a few powerful ones within the past couple years, and they often occur in my mind's eye while in between a state of asleep and awake.
Early one morning, for example, I was shown a series of images flashing in my mind of what appeared to be otherworldly environments and enormous structures not of this Earth. Then the scene shifted, and it was almost like a movie playing in my mind of this odd-shaped craft hovering within close range over this road environment. I simply watched as it performed a few circles before it landed, and the doors began to open, but I didn't get to see the actual beings. The craft itself was shaped like an inverted pyramid, and only later did I grasp the symbolic significance as to why it could have been shaped like that, but that might be personal to me.
I've had some really cool experiences whether in sleep paralysis or astral states, at least a couple times where this female figure was whispering down at me and I was going in and out of my body as if I was bilocated -- out of my body I could sense her energy (although it was dark) and hear her whispering clearly, she even called my name in a reassuring way when I began to get a little anxious. Still don't know exactly who it was, but I've had that same experience with her twice. It's not all positive, however, because one time when I was in a negative state I woke up to a shadow being staring down at me. Funnily enough, I wasn't scared but simply angry. I realized that I was out-of-body and chased it around my astral room, shooting light at it from my hands. It sounds kind of crazy just typing this out but the experience itself was real.
Whether in a lucid dream or astral plane, whatever you want to call it, you can have some cool visions if you find a mirror and see your vivid astral reflection. Ask questions to the mirror and you can see yourself shift. For example, "show me who I really am." I've asked this a couple times to an astral mirror and ended up both times with powerful symbolic messages, though again that might be a bit personal.
Finally, a couple months ago I felt the energy of a being at my bedside standing by the window. Again I couldn't really see the being clearly but I could feel its presence, and I spoke words automatically as if it was channeling through me: "The truth is that it's not nonsense," it transmitted through me. For an hour afterwards I was trying to figure out what that meant, what it was referring to. Only when I watched a video on youtube that morning while still in bed I understood the message, for the video (which I had previously never seen) featured Dr. Michael Salla affirming about the gradual ET disclosure "it is going to be a seismic shift for people who have dismissed the whole UFO phenomenon as nonsense." And that was my aha! moment.
It is not all fantastical, however. Sometimes it is very simple with a fleeting image. Just this morning I had the image in my mind's eye of a cup emptying out a tiny bit of liquid. I had no idea what that meant until later when I checked youtube, and saw a promoted video by Joel Osteen, who I don't even watch, but that's besides the point. The video was entitled "Empty Out The Negative," so I made sense of the flash I was given earlier. Things like this happen pretty often.
I think we are all being contacted to some degree, we just have to become aware of it and take time to really analyze our thoughts and where they come from.
